We handle two major issues in applying extreme value analysis to financial time series, bias and serial dependence, jointly. This is achieved by studying bias correction method when observations exhibit weakly serial dependence, namely the β−mixing series. For estimating the extreme value index, we propose an asymptotically unbiased estimator and prove its asymptotic normality under the β−mixin...

In this paper the diffusion entropy technique is applied to investigate the scaling behavior of financial markets. The scaling behaviors of four representative stock markets, Dow Jones Industrial Average, Standard&Poor 500, Heng Seng Index, and Shang Hai Stock Synthetic Index, are almost the same; with the scale-invariance exponents all in the interval 1⁄20:92; 0:95 . We also estimate the local...

In a previous paper (Baron and Vaughan Jones, 1958) we discussed the difficulties of estimating the prevalence of gastric and duodenal ulcer. We concluded, as had Doll (1952), that a population survey was the method of choice, and we studied the whole British Army of 1955. Some of our findings were sufficiently different from those of British and other civilians for us to seek anotherlarge popu...

Few doctors working in the accident and emergency (A&E) department will have had experience in the management of adder (Vipera Berus) bites. While such events are uncommon, and rarely fatal, prompt correct management undoubtedly helps in reducing mortality and morbidity. Various isolated case reports (Watson & Harland, 1977; Gerard & Pugh, 1982; Jones & Clegg, 1985) and larger reviews (Reid, 19...

Rheumatic heart disease is still a relevant problem in children, adolescents and young adults. Molecular mimicry between streptococcal and human proteins has been proposed as the triggering factor leading to autoimmunity and tissue damage in rheumatic heart disease. Despite the widespread application of Jones' criteria, carditis is either underdiagnosed or overdiagnosed. Endocarditis leading to...
